Why Building a Pattern Library Isn’t Just a Dev Task

A pattern library needs people who write content and design pages as well as people who write CSS. Otherwise we end up with components that look fine in isolation and don't quite fit the work.

I'd start with a real page and agree which parts are worth sharing. Give those parts names everyone recognises. Include the long heading and the awkward error message in the examples. A library is much easier to discuss when it contains things people actually need to publish.
